Product Description

Veinasa-ZFS PV System Used Solar Radiation Sensor Solar Radiation Pyranometer for Automatic Solar Energy Tracking

Product Description

The solar radiation sensor (also called pyranometer) measures solar energy from the sun.

 

Veinasa-ZFS PV System Used Solar Radiation Sensor Solar Radiation Pyranometer for Automatic Solar Energy Tracking is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. The spectrum of solar radiation is close to that of a black body with a temperature of about 5800 K. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum. The units of measure are Watts per square meter.

Applications:
The device is typically used in agricultural applications, and is used in the calculation of Evapotranspiration. Evapotranspiration is the potential for evaporation of moisture from the soil (or the reverse of rainfall) and is a function solar energy, wind and temperature.

Why Measure Solar Radiation?

Atmospheric circulation is driven by solar radiation.

Determining the solar radiation and its interaction with the atmosphere and the Earth's surface is important, since solar radiation accounts for almost all of the energy available to the Earth. There are two ways solar radiation reaches the Earth's surface.

The first is direct solar radiation where the solar radiation is directly transmitted through the atmosphere. The second is diffuse solar radiation where the incoming solar radiation is scattered or reflected to the Earth's surface.

Almost 50% of shortwave solar radiation is absorbed by the Earth's surface and changed into thermal infrared radiation.

Direct solar radiation is measured by using solar radiation sensors or pyranometers. These type of solar radiation sensors have a transparent hemisphere which measures the total amount of shortwave solar radiation.

Solar radiation sensors or pyranometers measure the total radiation or sum of the direct radiation and the diffuse solar radiation.
